 * $Log: base_val.h,v $
 * Revision 1.24  2023/06/28 10:04:32  j_novak
 * Use of C++ strings and flows instead of C types.
 *
 * Revision 1.23  2014/10/13 08:52:31  j_novak
 * Lorene classes and functions now belong to the namespace Lorene.
 *
 * Revision 1.22  2014/10/06 15:09:39  j_novak
 * Modified #include directives to use c++ syntax.
 *
 * Revision 1.21  2013/06/05 15:10:41  j_novak
 * Suppression of FINJAC sampling in r. This Jacobi(0,2) base is now
 * available by setting colloc_r to BASE_JAC02 in the Mg3d constructor.
 *
 * Revision 1.20  2013/01/11 08:20:10  j_novak
 * New radial spectral bases with Legendre polynomials (R_LEG, R_LEGP, R_LEGI).
 *
 * Revision 1.19  2012/01/17 10:18:17  j_penner
 * changed nzone from a private member to a protected member
 *
 * Revision 1.18  2009/10/23 12:55:46  j_novak
 * New base T_LEG_MI
 *
 * Revision 1.17  2009/10/08 16:19:32  j_novak
 * Addition of new bases T_COS and T_SIN.
 *
 * Revision 1.16  2008/12/03 15:21:20  j_novak
 * New method mult_cost.
 *
 * Revision 1.15  2007/12/11 15:28:05  jl_cornou
 * Jacobi(0,2) polynomials partially implemented
 *
 * Revision 1.14  2005/09/07 13:09:48  j_novak
 * New method for determining the highest multipole that can be described on a 3D
 * grid.
 *
 * Revision 1.13  2004/11/23 15:03:14  m_forot
 * Corrected error in comments.
 *
 * Revision 1.12  2004/11/04 15:39:45  e_gourgoulhon
 * Modif documentation: added description of bases without any symmetry
 *  in theta.
 *
 * Revision 1.11  2004/08/24 09:14:40  p_grandclement
 * Addition of some new operators, like Poisson in 2d... It now requieres the
 * GSL library to work.
 *
 * Also, the way a variable change is stored by a Param_elliptic is changed and
 * no longer uses Change_var but rather 2 Scalars. The codes using that feature
 * will requiere some modification. (It should concern only the ones about monopoles)
 *
 * Revision 1.10  2004/03/22 13:12:40  j_novak
 * Modification of comments to use doxygen instead of doc++
 *
 * Revision 1.9  2004/01/27 14:31:25  j_novak
 * New method Base_val::mult_sint()
 *
 * Revision 1.8  2004/01/27 14:13:58  j_novak
 * Added method Base_val::mult_x()
 *
 * Revision 1.7  2003/10/20 06:41:43  e_gourgoulhon
 * Corrected documentation.
 *
 * Revision 1.6  2003/10/19 19:42:50  e_gourgoulhon
 * -- member nzone now private
 * -- introduced new methods get_nzone() and get_b()
 * -- introduced new methods name_r, name_theta and name_phi.
 *
 * Revision 1.5  2003/09/16 08:53:05  j_novak
 * Addition of the T_LEG_II base (odd in theta, only for odd m) and the
 * transformation functions from and to T_SIN_P.
 *
 * Revision 1.4  2002/10/16 14:36:28  j_novak
 * Reorganization of #include instructions of standard C++, in order to
 * use experimental version 3 of gcc.
 *
 * Revision 1.3  2002/09/13 09:17:31  j_novak
 * Modif. commentaires
 *
 * Revision 1.2  2002/06/17 14:05:15  j_novak
 * friend functions are now also declared outside the class definition
 *
 * Revision 1.1.1.1  2001/11/20 15:19:27  e_gourgoulhon
 * LORENE
 *
 * Revision 2.20  2001/10/12  14:56:09  novak
